A process for removing asphaltenes from an oil feed comprising the steps of introducing the oil feed to a reactor, where the oil feed comprises a carbonaceous material and asphaltenes, introducing a heteropolyacid feed to the reactor, where the heteropolyacid feed comprises a heteropolyacid, operating the reactor at a reaction temperature and a reaction pressure for a reaction time such that the heteropolyacid is operable to catalyze an acid catalyzed polymerization reaction of the asphaltenes to produce polymerized asphaltenes, where a mixed product comprises the polymerized asphaltenes and a de-asphalted oil, introducing the mixed product to a separator at the end of the reaction time, and separating the mixed product in the separator to produce a de-asphalted oil and a waste stream, where the de-asphalted oil has a lower concentration of sulfur, a lower concentration of nitrogen, and a lower concentration of metals as compared to the oil feed.

Methods for separation of oxygenates or other chemical components from fuels using chemical processes and separations including, but not limited to, onboard applications in vehicles. These separations may take place using a variety of materials and substances whereby a target material of interest is captured, held, and then released at a desired location and under desired conditions. In one set of experiments we demonstrated an enhancement in the separation of diaromatics by >38 times over gasoline and aromatics by >3.5 times over gasoline. This would give an advantage to reducing cold-start emissions, or emissions during transient conditions, in either gasoline or diesel.

Treatment systems, agents and processes are described for processing polluted oil sludge into environmentally harmless and reusable resources. The oil sludge is first crushed, mixed with water, stirred, and stratified, then the overflow layer with the oil slick is transferred into oil recovery tank; the remaining mixture of solid and liquid is then subjected to centrifugal solid-liquid separation, the resulting free water is collected for reuse through osmosis, and the remaining solid phase material goes through a secondary oil content reduction treatment, adding water, degradable treatment agent, stirring, and after the system was standing stratified, the upper layer with the oil slick is overflowed and transferred to oil recovery tank; for the mixture from the centrifugation separation and reduction treatment processes, the resulting liquid phase is subjected to oil water separation, the oil phase is transferred into the oil recovery tank, the water phase enters into the wastewater recycling tank for recycle and reuse, the remaining solid phase is treated to become environmentally harmless materials; undergo centrifugal separation again, and the liquid phase is distilled to recover the plant based treatment agent, the remaining oil is transferred to the oil recovery tank, and the excess sludge is dried.
